saturated fat heart disease

Almost a decade ago, In 2010, Siri-Tarino and colleagues published a meta-analysis of prospective cohort studies evaluating the association between dietary saturated fat and cardiovascular disease in the American Journal of Clinical Nutrition. Based on the results of this meta-analysis, these researchers concluded that there was insufficient evidence from prospective cohort studies to conclude that dietary saturated fat increases the risk of coronary heart disease. However, a number of prominent diet-heart researchers identified many serious flaws and omissions in this meta-analysis that cast doubt on the validity of these researchers conclusions.

More recently, Chowdhury and colleagues published a separate meta-analysis in the Annals of Internal Medicine, and reached similar conclusions to that of Siri-Tarino and colleagues regarding the association between saturated fat and coronary heart disease. Unfortunately, this meta-analysis also failed to sufficiently address a number of important limitations that it shares with the meta-analysis by Siri-Tarino and colleagues. Furthermore, in this meta-analysis, although positively, but not significantly associated in the random-effects model, both dietary and total circulating concentrations of saturated fat were associated with a small, but statistically significant increased risk of coronary heart disease in the fixed effects model (RR=1.04 [95% CI, 1.01, 1.07] and RR=1.13 [95% CI, 1.03-1.25], respectively). These significant findings were however ignored in the conclusions of this study. Nevertheless, the media and proponents of popular Low-Carb and Paleo diets have repeatedly cited these meta-analyses as evidence to support a diet rich in saturated fat.

Saturated fat is not only a problem?

The findings reviewed by them support the hypothesis that saturated fat increases the risk of coronary heart disease mortality. Furthermore, as reviewed previously, evidence also suggests that the hazardous effects of diets rich in saturated fat are also applicable to diets rich in organic, grass-fed animal foods. However, saturated fat is only one of a number of problems as far as chronic diseases are concerned. The effect that a particular food has on the risk of coronary heart disease cannot be fully explained by saturated fat content alone, but rather by multiple nutrients that likely operate together in a complex manner to modify the risk of disease. Therefore, it may be more appropriate to focus attention on recommending healthy dietary patterns that are naturally low in saturated fat, while rich in dietary fiber and other beneficial nutrients; primarily, minimally processed, plant-based diets. Such a focus may be more effective to help lower the intake of saturated fat, while simultaneously improving overall dietary quality compared to the more contemporary reductionist approach of focusing on modifying single nutrients.

Only saturated fat intake cannot be responsible for heart disease – balance diet is required with lower saturated fat.

Big fat lies?

    You got me there. If people are living longer, there’s really no reason to point that the Lipid Hypothesis is wrong, that the anti-fat scare has made people fatter and diabetic and put them on loads of needless drugs. Hey, we’re living longer, so we don’t care if spend those extra years doped up and sick all the time! Stop complaining!

    Excellent point.

    Yup, and if we combined our medical technology with not eating junk (sugar and starch) people in the US would live even longer.

    ha, no chance of that! I get parts of it stuck in my head… particularly the “would you like a hot fudge sundae?” “would you like a hot apple pie?” “would you like a large order of fries?” part. you’re a funny guy!

    I have a question for ya though, Tom. I’m fine with animal fat, coconut oil, olive oil, nuts, seeds, fruits n veggies. But what about dairy products? I don’t wanna throw a common vegan argument at you but we’re the only species that drinks another species’ milk, and the only one that drinks it past childhood. Not to mention dairy’s been blamed for acne, which I have and want to get rid of. Are cheese, butter, and whole milk REALLY natural foods we’ve eaten for millions of years?

    Not to mention, if you cut carbs out of the equation, the asian diet is practically sugar free. Americans hate their desserts because they don’t taste as sweet as they’re used to. Asians come to America and think EVERYTHING tastes like sugar.

  9. FatHeadMovie says:

    Sugar and starch have way more to do with acne than dairy.

    We clearly don’t need dairy products. Hard-core paleo eaters don’t consume them. But roughly half of us tolerate them just fine or even benefit from them — the necessary genetic mutation occurred thousands of years ago, mostly in Europe.

    What’s considered an intolerance to dairy is often only a reaction to homogenized/pasteurized milk products. I eat raw-milk cheese now, and it’s very easy to digest.

    silver water/coloide/mms wil get rid of acne as it is only a bacteria in ur blood. they will kill all known stuff that should not be ther !

    @unknownperson3333 till we come up with a way to live forever. we are all kinda dying so that isnt the point. but just so you know which side im on (yours or someone elses) due to fucked up food i had to have my gallbladder taken out. which the surgery was fucked up on. now im in constant pain and the doctors WONT help me. so fuck doctors and fuck the people who make this trash food we eat today

  22. Can someone help me out, this guy says we’ve only been farming and eating grain since yesterday, humans have been eating grain (bread) since the neolithic days, it’s the oldest food, did I miss something?

    Agriculture began about 12,000 years ago and only spread to some parts of the world 5,000 years ago. Humans have been around in one form or another for millions of years.

    Bread is by no means the oldest food.

  28. Yes, in fact I think the same thing applies to milk, we begun drinking milk with cattle domestication, not before.

    One might think this video is an oversimplification, but honestly the first 30 seconds or so tells all you really need to know.

    Me too – the raw dairy. When I drink regular milk, even the organic stuff, It is flatus city:-).

    However, when I drink the raw, grass-fed, unpasturized and un homogenized stuff I am completely fine.

    They both have lactose, so it can’t be the probelm.

    The problem with this is that we use to only live to the age of 35 or 40 mainly due to disease and poor hygiene. You can’t compare past dietary lifestyles to today. That being said, Fat is and has been way over-inflated as a cause of poor health. It is the processed foods (chips & sodas) and a sedentary existence that are the real culprits. Eat less. That’s the mantra. Less is More, when it comes to food.

  36. can you get a version for europe?

    Thank you. I was a vegetarian for 8 years. I started eating meat 6 mos ago when I got pregnant. I’m getting into Paleolithic Nutrition thanks to my husband…and guess what?
    Since I’ve been eating more meat, veggies (protein & fiber) & fats, I’ve lost more weight! Definitely NO sugar!

    THANK YOU! The irony of it all!

    We’re working on it. Apparently the DVD distributors in other countries aren’t big on investing in little indie films. If nothing else, I’m going to try to make it available on iTunes overseas.

    @graftonreed Not true actually. Take out infant mortality and getting eaten by lions and we actually lived well into our sixties and seventies. One problem is that these paleolithic 60 & 70 year olds do not show the signs of degeneration in their skeletons that WE expect from people that old.

  48. graftonreed says:

    @ echelonfilms No, Archaeologist have determined that paleolithic life expectancy was about 33 years old. That’s not skewed by infant mortality rate, just the raw de facto results from excavations.
    That not withstanding…… believe what you want.
